The initial thought is that we'll have to patch both anaconda and
modprobe to be able to recognize and apply kernel module options passed
on the kernel command line. I'll be filing bugs against both
module-init-tools and anaconda shortly. Never say never, but getting a
fix in for the F7 release is highly, highly, highly unlikely.

So like I said, never say never... Jeremy has a dirty little hack for me
to try out in a sec... Stay tuned!
